Abstract EN
In this paper, shear behavior of reinforced hybrid concrete connection of corbel-column is experimentally investigated.
Nine homogenous and hybrid concrete corbel-column connections subjected to vertical applied loads were constructed and tested within two test groups (A, B).
The experimental program included the effect of several variables such as type of hybrid concrete;high strength concrete (HSC) or steel fiber reinforced concrete (SFRC), monolithic casting of hybrid concrete connection, and presence of construction joint at the interface of corbel-column.
Experimental results showed significant effects of concrete hybridization on the structural behavior of connection specimens such as: ultimate strength, cracking loads, cracking patterns, and failure modes.
Hybridization process in group (A) included hybrid connection of corbel-column with HSC or SFRC corbel instated of NSC.
This process led to increase the capacity of connection by (26%, 38%) and shear cracking loads by (20%, 120%) respectively.
Moreover, connections of hybrid concrete corbels cast monolithically improved the shear capacity of corbels by (19%, 42%) for HSC or SFRC respectively.
In group (B), presence of construction joint at connection region reduced the shear capacity of connectionsby (10% to 22%) and cracking loads by (23%-62%) compared with connections cast monolithically.
